Abstract

Motor-driven, adjustable supporting device for the upholstery of seating and/or reclining furniture, e.g. a mattress or a bed, has a first supporting part and at least a second supporting part for the support of a mattress over its surface. The first supporting part and the second supporting part are jointedly connected to one another and are pivotable relative to one another by a drive. The drive may have at least one electromotive drive which is disposed on the first supporting part in such a way that an output element of the drive is disposed between an upper limiting plane and a lower limiting plane of the first supporting part.

Claims

1. An adjustable supporting device for upholstery of one of seating and reclining furniture, comprising:

a) a first supporting part defining an upper limiting plane and a lower limiting plane;

b) at least a second supporting part disposed adjacent the first supporting part for the support of a mattress over its surface;

c) the first supporting part and the second supporting part being jointedly connected to one another and pivotable relative to one another;

d) an electromotive drive disposed on the first supporting part;

e) the electromotive drive including an output element operatively associated with the first and second supporting parts for pivoting the first and second supporting parts relative to each other; and

f) the electromotive drive being disposed between the upper limiting plane and the lower limiting plane of the first supporting part.

2. Supporting device according to claim 1, wherein:

a) the drive is disposed essentially completely between the upper limiting plane and the lower limiting plane of the first supporting part.

3. Supporting device according to claim 1, wherein:

a) the first supporting part includes at least one side bar formed as a hollow profile and the drive is accommodated in the hollow profile.

4. Supporting device according to claim 3, wherein:

a) the drive is removably connected to one of the side bars.

5. Supporting device according to claim 1, wherein:

a) the drive is disposed between lateral limiting planes of the first supporting device.

6. Supporting device according to claim 4, wherein:

a) the drive is accommodated in a housing.

7. Supporting device according to claim 6, wherein:

a) the housing is connected to one of the side bars and a cross bar of the first supporting device.

8. Supporting device according to claim 6, wherein:

a) two drives are disposed in the housing in such a way that a double drive is formed.

9. Supporting device according to claim 3, wherein:

a) the supporting part has two side bars spaced relative to one another in the transverse direction of the lath grid, and each side bar is assigned to a housing in which at least one linear-motion drive is accommodated.

10. Supporting device according to claim 1, wherein:

a) the drive is a linear motion drive; and

b) the output of the drive is movable substantially in the longitudinal direction of the supporting device.

11. Supporting device according to claim 1, wherein:

a) the drive is a linear-motion drive.

12. Supporting device according to claim 11, wherein:

a) the output of the linear-motion drive is a spindle nut which is held, secure against rotation and movable in the screw direction, on a threaded spindle rotatably drivable by the drive, which is an electric motor, and the spindle nut is in functional connection with a lever mechanism for pivoting at least one of supporting part relative to the first supporting part.

13. Supporting device according to claim 12, wherein:

a) the threaded spindle is disposed essentially parallel to the drive shaft of the electric motor of the linear-motion drive and is in functional connection with it via gearing.

14. Supporting device according to claim 1, wherein:

a) the first supporting part is formed by a central supporting part and the second supporting part by an upper body-supporting part, and a leg-supporting part is provided which is connected, jointedly and pivotably about a pivot axis essentially parallel to the pivot axis of the upper body-supporting part, to the central supporting part on its side opposite its upper body-supporting part.

15. Supporting device according to claim 14, wherein:

a) a head-supporting part is provided which is connected, jointedly and pivotably, about a pivot axis essentially parallel to the pivot axis of the upper body-supporting part, to the upper body-supporting part on its side opposite its central supporting part.

16. Supporting device according to claim 14, wherein:

a) a calf-supporting part is provided which is connected, jointedly and pivotably, about a pivot axis essentially parallel to the pivot axis between the central supporting part the leg-supporting part, to the leg-supporting part on its side opposite the central supporting part.

17. Supporting device according to claim 1, wherein:

a) one of the first and second supporting parts includes a lath grid.

18. Supporting device according to claim 1, wherein:

a) the reclining furniture includes a mattress.

19. Supporting device according to claim 1, wherein:

a) the reclining furniture includes a bed.

20. Supporting device according to claim 3, wherein:

a) the reclining furniture includes a bed.
